The most universal type mine ever to be used was created in 1918. Live versions
were used extensively during both WW I and WW II. The North sea saw the
majority of them, and unfortunately Scottish fishermen still come home every
so often with a live one hung in their nets!

The traditional ball and spike mine has been depicted in movies all over the
world
as THE MINE that all fear the most. Many other countries have copied the basic
design and created their own versions. The Iraqis even used their version of the
Soviet M-08, similar but smaller than the US MK 6, during the Gulf war.

US MK 6 mines contained TNT type explosive and were operated by contact switch
horns. Today the Mk 6 is used extensively as a training mine because it immolates
the shapes of mines used predominately by opposing forces.
